Magnetic Surface Thermocouple 72" fiberglass extension J type

The Series M Magnetic Surface Thermocouples are commonly used for temporary measurements of surface temperatures of ferrous materials. A powerful Alnico Magnet presses the spring-loaded sensor tip against the surface to be measured. The magnet has a holding force of 16 lbs and can withstand up to 1000°F (535°C) without any degradation.
